fix: path-form listing routes use the SEO module's resolved pagination

- journalPaginationSource answers runtimeConfig.public.seo.pagination (the
  SEO module's option with its defaults), else the raw seo.pagination
- the module computes the paged routes inside its extendPages callback, so
  an app with only form: 'path' gets /blog/strona/:page and
  /blog/page/:page (L4 WR-03)
